Aqua Ultraviolet

Aqua Ultraviolet is a California-based manufacturer of UV water sterilizers, Ultima II water filtration systems and UV air sterilizers, building chemical-free water treatment equipment in the USA since 1985. For more than 40 years, we have helped customers get cleaner, clearer water without adding chemicals or changing the natural characteristics of their water. We also supply replacement UV lamps and parts, so your system keeps performing at its best year after year.

Our product range covers a wide variety of needs. UV sterilizers treat drinking water, well water, koi ponds, water gardens, aquariums, aquaculture, pools and spas, and greenhouses. Ultima II filters are designed for exceptional water clarity, easy maintenance and long-lasting performance. Our UV air sterilizers, from compact plug-in units for a single room to whole-home systems that connect to your air duct system, help improve air quality in residential and commercial spaces.

Our systems are made for homeowners with city or private well water, koi pond and aquarium keepers, aquaculture operators, pool and spa owners, greenhouse growers, and commercial and industrial users.

We are based in Murrieta, California, and support customers across the United States with sizing help, product support and warranty registration. Our UV sizing calculator and sizing charts make it easier to match the right system to your water flow and application.

Customers choose us for 40+ years of UV experience, Made-in-USA quality, a limited lifetime warranty on every product, reliable and easily serviceable equipment, and a support team ready to help you choose the right system.
